(2014-07)Newly received calves that received antimicrobial treatment for bovine respiratory disease (BRD) were randomly assigned to 1 of 4 experimental ancillary therapy (ANC) groups: flunixin meglumine (NSAID), viral vaccination ... -
Assessment of the diversity, abundance, and ecological distribution of members of candidate division SR1 reveals a high level of phylogenetic diversity but limited morphotypic diversity
(American Society for Microbiology, 2009-06)We used a combination of 16S rRNA gene clone library surveys, quantitative PCR (qPCR) analysis, and fluorescent in situ hybridization to investigate the diversity, abundance, and distribution of members of candidate division ... -
Black-tailed Prairie Dog and Large Ungulate Response to Fire on Mixed-grass Prairie
(Oklahoma State University, 2010-12-01)Restoring historic fire-grazing regimes and the declining keystone species the black-tailed prairie dog (Cynomys ludovicianus) are two management priorities in North America's grasslands. My study sought to investigate the ... -
Determination of the mechanism(s) by which direct-fed microbials control Escherichia coli O157:H7 in cattle
(2009-05)Scope and Method of Study: The purpose of this experiment was to investigate the possible mechanisms responsible for the success of the direct-fed microbials, Lactobacillus acidophilus and Propionibacterium freudenreichii ... -
Development of a Multi-Scale Walkover Platform for Precision Livestock Management
(2019-05-01)Stocker Cattle Operations are a vital part of the beef cattle industry in Oklahoma. One of the most vital pieces of information for a stocker cattle operation is the weight of each individual management. Walkover Scales ... -
Development of Technology to Exclude Feral Animal Feed Consumption from Calf Creep Feeders
(Oklahoma State University, 2011-12-01)A series of experiments was performed with the objective of creating a system to exclude feral animals from calf creep feeders. The first experiment evaluated three different electronic sensor systems for accuracy of ... -
Effect of a transitional diet on stocker heifers grazing wheat pasture
(2020-05)Cattle on wheat pasture require an acclimation period before significant body weight gains occur. Weight loss is often observed during the adaptation period. The effect of energy supplementation while grazing wheat has ... -

Effect of increased ruminal proprionate on the expression of hepatic gluconeogenic genes in cattle on a finishing ration
(Oklahoma State University, 2022-04-19)The objective of this experiment was to ascertain if supplementing calcium propionate (CaP) in varying amounts would result in the increased expression of genes related to glucose metabolism in the liver. The study utilized ... -
Effects of Wet Distillers Grains Plus Solubles and Energy of the Health and Performance of Receiving Calves
(Oklahoma State University, 2012-12-01)A randomized complete block design experiment utilizing 180 high-risk crossbred steers (initial BW = 212 ± 2 kg) was conducted to evaluate the effects of including wet distillers grains plus solubles (WDGS) in a 62% ... -
Estimated Impacts of Mexican Regional Trade Restrictions Associated with Bovine Health Campaigns
(Oklahoma State University, 2006-12-01)Tuberculosis restrictions on animal movement have important implications for Mexican producers and consumers as well as the U.S. beef cattle industry. A spatial linear programming model was used to analyze scenarios of ... -
Evaluation of Byproduct Combinations on Feedlot Performance, Carcass, and Fecal Characteristics
(Oklahoma State University, 2012-07-01)The first experiment compared inclusion levels of a 1:1 blend of Sweet Bran (SB) and dried distiller's grains (DDGS) byproducts in a dry-rolled corn feedlot ration on performance, carcass merit, and fecal characteristics. ... -
Evaluation of Diet Adaptation Programs and Supranutritional Dietary Antioxidants for Feedlot Cattle
